Clark Hoyt discusses the resignation of former New York Times business reporter Zachary Kouwe. Once again, the Kouwe affair embroiled the Times in questions about its ability to police its own. Says Mr. Hoyt,

Though Kouwe was gone the next day, questions remain: How did his serial plagiarism happen and go undetected for so long? Why were warning signs overlooked? Was there anything at fault in the culture of DealBook, the hyper-competitive news blog on which Kouwe worked? And, now that the investigation is complete, what about a full accounting to readers?

As Mr. Hoyt notes, online journalism poses its own problems in addition to those it inherits from traditional journalism. How does the press deal with those?
